[slurm-users] Slurm and MPICH

MPICH uses the PMI 1 interface by default, but for our 20.02.3 Slurm installation, "srun -mpi=list yields"

$ srun --mpi=list
srun: MPI types are...
srun: cray_shasta
srun: pmi2
srun: none

PMI 2 is there, but not PMI 1.   Does this indicate that we need to rebuild Slurm to support PMI 1?
